I can trade Best for a WR - help me put together a deal

[sirsydney]

I've been shopping Best for a WR upgrade. This owner has S. Johnson & Colston, and needs a RB. League is .5 PPR and here's his roster:

QB: Brady, Newton
WR: S. Johnson, Colston, Ginn, N. Washington, Doucet
RB: MJD, D. Williams, McCluster, M. Bush, Battle
TE: Gonzalez,
K/DST: Crosby, HOU

Who would you target? S. Johnson or Colston? Would you do a 1 for 1 (Johnson/Colston for Best), or what?
My RBs are: Rice, Forte, Best, Torain, Ridley
My WRs are: Marshall, Harvin, D. Moore, D. Baldwin

Leave a link and I'll help. Thanks!
===============================
(12-team league) (.5 PPR) (KR yardage 1/15yds)
QB - Stafford, Tebow
WR - Marshall, Harvin, Baldwin, D. Moore
RB - Rice, Forte, Best, Torain, Ridley
TE - Olsen, Gates
K- Hanson
DST - DET

1. Number of teams are in your league = 10
2. How many of each position you start = 1 QB, 2 WR, 2 RB, 1 TE, 1 W/R, 1 K, 1 DEF
3. The size of your roster = 9 active, 6 bench
4. Your league's scoring system
PPR = 0.5
Pass TD = 4
TD = 6
FG = 3, 40+, 50+
All yardage (KR included) = 15 yds/ 1 point
Sacks = 1
Int/Fum = -1/-2

Current trade on the table is Best/Harvin for S. Johnson/Colston - fair? not enough?

I am not a fan of Colston so I don't like the deal. I think you could get a better WR for Best if you really want to get rid of him
